[Bug 2073876] [NEW] fontconfig-config's 40-generic.conf is a legacy file since 2007 (please update)

Tue Jul 23 11:56:07 UTC 2024

Public bug reported:

I saw lots of errors during application startups:

```
Fontconfig warning: "/etc/fonts/conf.avail/40-generic.conf", line 27: Having multiple <family> in <alias> isn't supported and may not work as expected
..
Fontconfig warning: "/etc/fonts/conf.avail/40-generic.conf", line 50: Having multiple <family> in <alias> isn't supported and may not work as expected
..
Fontconfig warning: "/etc/fonts/conf.avail/40-generic.conf", line 66: Having multiple <family> in <alias> isn't supported and may not work as expected
..
```

So I went Googling and found this forum from 2015: https://forum.tinycorelinux.net/index.php/topic,18006.0/
Which links to this page: http://www.cromwell-intl.com/linux/font-config-warnings.html
Which is now at: https://cromwell-intl.com/open-source/font-config-warnings.html

It proposes a fix. Of course you *may* apply it.

But I went looking further, if I could report this to the original
fontconfig source.

And there I found for fontconfig 2.4.92 (6 November 2007):
https://gitlab.freedesktop.org/fontconfig/fontconfig/-/blob/main/NEWS#L2129

"Split 40-generic.conf into 40-nonlatin.conf and 45-latin.conf"

== What to do: ==

So maybe just remove 40-generic.conf from the package, and keep using
40-nonlatin.conf and 45-latin.conf

Just saying, but there's two more errors that I'm seeing. Maybe they
have a similar simple solution.

```
Fontconfig warning: "/etc/fonts/conf.avail/29-language-selector-ja-jp.conf", line 55: Having multiple values in <test> isn't supported and may not work as expected
Fontconfig warning: "/etc/fonts/conf.avail/29-language-selector-zh.conf", line 8: Having multiple values in <test> isn't supported and may not work as expected
```
